This simple and clean-lined lamp concept has been conceived by Chicago based designer Jacob Nitz. The Contour desk lamp is comprised of a single tubular metal structure, bent into an ergonomic shape. Here is how designer describes his idea:

As though it were a contour line tracing into space, it was created by a single steel tube. The self-supporting structure utilizes a warm, white LED light strip in a pivotal armature allowing for versatile lighting options. 

I like that instead of hiding the cord, Nitz decided to accentuate it with colour. And because the lamp itself comes in black, gray, blue, green, and red, multiple colour combinations can be achieved.
